About this conversion

Miles per imperial gallon and Liters per km are both units used to measure fuel economy. Miles per imperial gallon (mpg imp) measures how many miles a vehicle travels using one imperial (UK) gallon of fuel; a higher number means better efficiency. It is used mainly in the United Kingdom and other Commonwealth countries. Liters per kilometer (L/km) measures how many liters of fuel a vehicle consumes over one kilometer; a lower number means better efficiency. It is used for precise consumption tracking. Miles per imperial gallon is a distance-per-volume efficiency unit while liters per km is a volume-per-distance consumption unit, so converting between them means inverting the value rather than multiplying by a flat factor: 1 mpg imp = 2.824809363 L/km. This relationship stays accurate for automotive fuel efficiency ratings, vehicle comparisons and shopping, as well as EPA, WLTP and other international fuel economy standards.
